Abstract
A coil component comprising a winding core portion. When one of side surfaces of the winding core portion is a specific side surface, a 35th turn of a second wire has a first crossing point where the 35th turn of the second wire on an outside of a 35th turn of a first wire crosses the 35th turn of the first wire on the specific side surface. A part of the 35th turn of the second wire closer to a second wire end than the first crossing point is wound around an outside between a 34th turn of the first wire and a 34th turn of the second wire adjacent to the 34th turn of the first wire in a direction along a central axis on the specific side surface.

A coil component comprising:
- a winding core portion having a polygonal prism shape;
- a first flange portion at a first end of the winding core portion in a direction along a central axis of the winding core portion;
- a second flange portion at a second end of the winding core portion opposite to the first end;
- a first outer electrode and a second outer electrode that are on the first flange portion;
- a third outer electrode and a fourth outer electrode that are on the second flange portion;
- a first wire wound around the winding core portion, the first wire having a first wire end and a second wire end, the first wire end of the first wire being connected to the first outer electrode, the second wire end of the first wire being connected to the third outer electrode;
- and
- a second wire wound around the winding core portion in the same direction as the first wire, the second wire having a first wire end and a second wire end, the first wire end of the second wire being connected to the second outer electrode, the second wire end of the second wire being connected to the fourth outer electrode, wherein
- each time the first wire is wound around the central axis in a direction from the first wire end toward the second wire end and forms one turn, a number of turns of the first wire increases by one,
- each time the second wire is wound around the central axis in a direction from the first wire end toward the second wire end and forms one turn, a number of turns of the second wire increases by one, and
- when one of side surfaces of the winding core portion is a specific side surface,
- a j-th turn (j is an integer of 2 or more) of the second wire has a first crossing point where the j-th turn of the second wire on an outside of an i-th turn (i is an integer of 2 or more) of the first wire crosses the i-th turn of the first wire on the specific side surface, and
- a part of the j-th turn of the second wire closer to the second wire end than the first crossing point is wound around an outside between a specific turn of the first wire and a turn of the wire adjacent to the specific turn in the direction along the central axis of the winding core portion on the specific side surface.
